I can't speak for that USB to serial adapter, But I have had good luck 
with them, including using with NUT to talk to UPS through Serial.  
<> that I carry in my laptop case and I know works great, I also have a few older ones that work great with FreeBSD (but not windows 7 or 8), but they are all at home so I can't grab the model from them.

The only issue I have had was having two identical USB to Serial 
adapters, on the same machine one for UPS, and one for Serial Console to 
pfSense firewall (on alix platform) they liked to switch order on 
reboot, despite the cables not being moved to different USB ports.
